When checking about:cache I find the information that the cache storage is at
/Users/grelber/Library/Caches/Firefox/Profiles/nar4skza.default/cache2
— but no matter what I do I cannot get into Profiles to access "cache2" (ie, access dead-ends at Profiles).
Ancillary query #1: How can I gain access?
The folder named
nar4skza.default (the alphanumeric ID is specific to your installation) is invisible, so to see what's within it you need to make it visible. No doubt this can be accomplished via various third-party uitilities such as OnyX, etc., but I just do it via Terminal.app thusly:
Launch Terminal. Type or copy & paste
defaults write com.apple.finder AppleShowAllFiles -bool YESand then hit Return.
With the Command and Option keys held down, click on Finder's Dock icon and choose Relaunch from the contextual menu. You'll notice the icons (if any) on your Desktop will disappear; once they're back, the relaunch is complete, and you can now navigate your way through the file hierarchy to your desired destination. (To reverse this action, follow exactly the same procedure, but substitute
NO for
YES in the Terminal command.)
I doubt it will be of too much use, though. My own
cache2/entries/ folder [wherein the goods appear to reside] contains (the suspiciously binary quantity of) 1024 items, all bearing completely obfuscatory names in the form
9A6C12FD9C956E553CB01BBDAAEE6234AE9DD55B, the majority of them documents like

(which, admittedly, can be identified as a NY Times item and therefore deleted if it's the Times whose cache you were looking to remove, but...), and the remainder an assortment of seemingly random graphics.
If there's a short way to separate the wheat from the chaff, I can't see it.
